Type ii restriction endonuclease from pseudomonas alcaligenes and a process for their preparation.

摘要

The present invention provides a novel Type II restriction endonuclease obtainable from Pseudomonas alcaligenes. The endonuclease known as PacI, recognizes the following nucleotide sequence and has a cleavage point indicated by the arrows: ##STR1## Also described is a process for obtaining PacI from P. alcaligenes.
